1. A03’s Advantage Zone: Lightweight Fogging for Instant Posture Intervention

The A03 Children’s Corrective Glasses (Smart Fogging Model) is one of SPAEXI’s first products in the children’s vision protection category. Its core feature is automatic fogging-based posture correction. When a child develops poor posture or excessively close reading distance, the lenses create a fogging change as a visual intervention, gently reminding the child to adjust their posture.

The main advantages of the A03 include:

1. Ultra-light wearing experience
   At only 32.6g, it is one of the lightest models in the A-series, placing minimal burden on the face of children aged 3–15 and suitable for long-term wear.

2. Instant visual feedback
   Fogging alerts are direct visual feedback that requires no sound or vibration, making them ideal for quiet environments such as classrooms and self-study sessions without disturbing others.

3. 40-hour battery life and magnetic charging
   It offers 40 hours of battery life in a lightweight body, paired with magnetic charging for multi-day use.

4. Affordable pricing
   A retail price of 499 RMB lowers the barrier for families to try smart vision protection products and supports market education.

The A03 can be positioned as: a lightweight smart glasses product for children’s posture correction, using fogging visual feedback for instant intervention, suitable for static scenarios such as classrooms, homework, and reading.

2. A07’s Advantage Zone: Multi-Dimensional Monitoring for Continuous Behavioral Correction

The A07 Children’s Corrective Glasses (Vibration Model) is an upgraded model launched by SPAEXI based on market feedback and technical accumulation from the A03. While retaining lightweight design and magnetic charging, it changes the alert method from “fogging” to “vibration” and expands the monitoring dimensions from single posture correction to three levels: distance, angle, and bright light.

The core advantages of the A07 are:

1. Multi-dimensional eye-care behavior monitoring

   • Distance monitoring: vibrates when reading distance is less than 30 cm;

   • Angle monitoring: vibrates when the head tilts more than 20° left or right;

   • Bright light detection: records outdoor bright light exposure time, providing parents with scientific prevention data.
     This multi-dimensional monitoring upgrades the A07 from a “posture correction tool” to an “eye-care habit management terminal.”

2. Non-intrusive alerts, suitable for more scenarios
   Vibration alerts do not disturb others and provide more direct tactile feedback, making them especially suitable for outdoor, sports, and mobile use, overcoming the limitations of fogging alerts in dynamic scenarios.

3. Ultra-long standby and no-app convenience
   The 110mAh lithium-polymer battery provides about 200 hours of standby time, with a full charge in about 1.5 hours. No smartphone or app is required; simply power on and automatic monitoring begins, greatly lowering the usage threshold for children and parents.

4. All-day applicability
   Weighing about 35g, the TR90/PC material is skin-friendly and wear-resistant, suitable for school, homework, reading, online classes, and outdoor activities.

The A07 can be summarized as: a children’s vision behavior intervention glasses designed for all-day wear, using vibration alerts for multi-dimensional real-time correction, suitable for home, school, and outdoor full scenarios.

3. How Did SPAEXI Upgrade from A03 to A07?

The move from A03 to A07 is not a simple model replacement, but a clear evolution of product logic in SPAEXI’s children’s smart wearable segment.

1. From “single alert” to “multi-dimensional monitoring”
   The A03 focuses on posture correction, while the A07 expands monitoring to reading distance, head tilt angle, and outdoor bright light duration, covering the major behavioral risk factors for children’s myopia.

2. From “visual alert” to “tactile alert”
   Fogging alerts are suitable for static and quiet scenarios, but provide weaker feedback in dynamic environments. The A07 switches to a vibration motor, making alerts more immediate, more private, and better suited to children’s outdoor and mobile usage habits.

3. From “screen dependence” to “power-on and use”
   The A07 insists on no smartphone and no app requirement, entering automatic monitoring mode upon power-on, leaving complex health management to algorithms while giving children and parents a simple user experience.

4. From “product” to “data entry point”
   The added bright light detection makes the product not only a passive reminder tool but also a terminal for recording children’s outdoor activity duration, providing data support for parents and future health management. This also reserves space for SPAEXI’s future expansion in the children’s health ecosystem.

4. Dual-Product Synergy: The Complementary Relationship Between A03 and A07

In SPAEXI’s children’s vision protection product line, A03 and A07 form a clear dual-product matrix:

This combination of “static + dynamic,” “visual + tactile,” and “single + multi-dimensional” enables SPAEXI to cover different families’ differentiated needs for children’s vision protection and provides channel customers with a richer product portfolio.

5. Industry Significance: A New “Behavioral Intervention” Path for Children’s Myopia Prevention

With growing national attention on student myopia prevention, children’s smart glasses are extending from “vision correction” to “behavioral intervention.” SPAEXI’s A-series does not choose complex display functions; instead, it focuses on three key behavioral indicators — reading distance, posture, and outdoor time — entering the market in a lightweight, simple, and affordable way. This “Warm Tech” approach lowers usage barriers while opening up scenarios closer to daily life for children’s smart wearables.

The upgrade from A03 to A07 reflects SPAEXI’s rapid iteration capability in niche markets — using user feedback to drive product evolution and differentiated features to build a product matrix. Going forward, as the A07 Vibration Model expands in the market, SPAEXI is expected to build stronger brand awareness and channel stickiness in the children’s vision health segment.
